Are these DIY beauty devices better than in-salon treatments? Our readers weigh in on the best at-home gadgets for hair removal, microdermabrasion, shrinking acne and more

What it is: Think of this little device as an industrial approach to tweezing. Tiny rotating discs catch a bunch of hair at once and yank it out at the root. It can be used on the face, arms, underarms, legs and bikini line.

Why it's great: Tired of shelling out for expensive wax sessions? Hate the short-term results of shaving? This epilator might be the answer to your hairless prayers. "I am completely in love and recommend it to all of my friends," says one convert. "I will never go back to shaving," says another. The epilator works by pulling out hairs with tiny rolling tweezers. Readers admit that it's a little painful, but say that the pain lessens with use. "I quickly got used to the pulling sensation, and eventually it stopped bothering me at all," says one reviewer.

Women also say this device saves them time and money. "It does take some time to do it, but if I have a spare hour, I can get smooth legs that last FAR longer than taking 10-15 minutes to shave every day," says one reviewer. "I usually pay the same amount just for ONE waxing session," says another. The best part? The epilator not only removes hair, but also discourages hair growth over time. "I've noticed that the more I epilate, the lighter and thinner my leg hair is coming back in," says a user.

Salon rate: It depends on where you go, but just a bikini (non-Brazilian) wax will run you around $40. Throw in two arms, two legs and your underarms, and you're looking at well over $200 per session. Annnd you'll have to go back every two to four weeks for another round.

Before you buy:You can return this device up to 30 days after purchase. This model of the Emjoi is rechargeable, so you won't have to replace batteries.
